INDICATOR FOR LOOMS.

s'rncrrrcmrron forming art of Letters Patent No. 687,365, dated November 26, 1901.

Application filed January 14, 1901. Serial No. 43,112. (No model.)

T0 aZZ whom it may concern:

Be it known that 1, JAMES FRANCIS Yarns, a citizen of the United States, residing at Paterson,in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Indicators for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to looms, and it has reference particularly to that class of attachments for machines of this nature which are adaptedfor registering the amount of goods produced, being commonly known as loomclocks. These devices are usually made in the form of a compact indicator, which is removably attached to some suitable part of the loom. In this form they are objectionable, either because they project out from the loom, so as to be in the way, or else because they cannot be secured in convenient reach of the eye of the operator, their con.- struction and that of the loom not always coacting to afford means suitable for this. In

order to overcome these difficulties-that is 1 to say, in order to place the indicator where it will not only be out of the way and thoroughly protected, but where it can be read at a glance by the weaver as he works-J propose to set the indicator down into some portion of the loom near which the weaver finds it necessary to most often be, such as the breast-beam, and it is in an indicator constructed with these and other objects (which will be hereinafter pointed out) in view that my invention consists.

The invention is fully illustrated in the accompanying drawings, wherein corresponding letters of reference indicate like parts, and wherein Figure 1 is a View in side elevation of the front portion of a loom constructed in accordance with my invention. Fig. 2 is a view in front elevation of that end portion of a loom which is shown in Fig. 1; and Fig. 3 is a top plan view of the breast-beam, showing the indicating device properly mounted therein.

In said drawings, a designates one of the side frames of the loom, and b designates the breast-beam, which, as usual, connects and braces the upper front portions of said side frames.

0 is the batten, and d the take-up roll, the parts for controlling which are not shown, since they have no bearing upon my invention.

e is the sand-roller, the same being disposed under the breast-beam, as usual, andf is an auxiliary roller disposed between the breast-beam and the sand-roller, the finished goods g being adapted to extend over the breast-beam, down under and around the sandroller, over and around the roller f, and onto the take-up roll.

In the upper face of one end of the breastbeam 17, preferably that end which is shown in the drawings, I have formed a recess or cavity 7t, with which at one end communicates an orifice 2', which extends vertically through the breast-beam. In the recess h is disposed a pair of gears j 75, one of them, the gear 7r, carrying a rigid pinion Z, which meshes with the teeth of the gear j. The gearj is journaled on a screw m, which penetrates a sleeve 17., upon which said gear rest-s. In said cavity is also arranged another pinion 0, which meshes with the gear 10. This pinion 0 is mounted on the upper end of a shaft 1), which extends through the orifice 2'. The upper end of the shaft 19 carries a pointer q, adapted to register on a circular index 1' some such units of measure as inches. The index is secured to the top of the breast-beam concentrically with the shaft 19, preferably by screws 3 and in such manner that it overlaps the gear k, and so, coacting with the gear j, holds said gear h in place. It should be remarked that as the pointer is adapted to register on the index inches or feet the gearj should be provided with indexes t, which by a stationary pointer to on the breast-beam may be made to show feet, yards, &c. On the shaft 9 is secured below and in approximate contact with the breast-beam a thrust-collar 'v. The shaft 1:) is stepped in a bracket 20, projecting from the frame a, and it carries at its lower end one of two bevel-gears 0c, the other of which, y, is secured on the shaft z of the sand-roller 6. Through the medium of the bevel-gearing the shaft 19 is rotated to operate the indicator. Any form of gearing, such as a Worm and worm-Wheel, may of course be used.

It should be remarked that by preference the indicator is mounted on the breast-beam, since this is the part of a loom near which the Weaver finds it necessary most often to be. By providing the cavity h in said breastbeam and making the depth of said cavity relatively greater than the thickness of the ceases roller thereof, of the breast-beam having a cavity formed in its upper face, a pair of gears arranged in said cavity and'one of them overlapping the other, a pinion carried by the overlapped gear and en gagingsaid first-named gear, a shaft projecting into said cavity, a pointer carried by said shaft, another pinion also carried by said shaft and engaging the overlapped gear, a dial secured on said breastbeam concentric with said shaft and overlapping said last-named gear, and power-transmitting mechanism connecting said shaft and the sand-roller, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of December, 1900.
